Quite a simple idea to prevent any PvP modes from becoming fully dead.

The new roulette would offer a substantial bonus once per day and include the following duties:
> The Feast (training match)
> Frontlines (freelance)
> Rival Wings

Basically the PvP version of the PvE mentor roulette, one that includes every kind of duty available. Would hopefully make RWings pop on the non-JP datacenters if people wait long enough, will fill with roulette people. Forced freelance should also reduce wait times for Frontlines.

edit: with a long term grind mount reward for clearing the roulette a large number of times
